Had they hit a woman or child, I doubt we would even be having this discussion.
Well, you are wrong.. but I will say.. The fact that we have this video in slow motion and zoomed in and still can't agree... is proof that the cops can be expected to be even far less certain in real time as to what he was doing.
Video is at a certain resolution, cops dealt with and saw the dood, I'm sure they saw more than us. That said, once the rounds started firing the first time, continuing to pull the trigger becomes less of a concious thought process.
